SPECIFICATION forming part of Letters Patent N 0. 643,692, datedFebruary 20, 1900. Application filed September 27, 1899. Seriallie-731,799. (No model.)

To all whom it may concern:

Be it known that I, BERNARD H. SPEOK- BAUCH, a citizen of the UnitedStates, residing at Newport, Campbell county, Kentucky, (post-officeaddress, 332 West Ninth street, Newport, Kentucky,) have inventedcertain new and useful Improvements in Printing- Presses, of which thefollowing is a specification.

This invention pertains to improvements in perfecting printing-pressesadapted for single-color or multicolor printing; and the improvementswill be readily understood from the following description, taken inconnection with the accompanying drawings, in WhlCl1- Figure 1 is asideelevation of a printingpress exemplifying my improvements; Fig. 2, aview from a similar direction, one of the housings being removed and theprinting, impression, and inking rolls appearing in vertical section inthe plane of line a of Figs. 4,

5, and 9; Fig. 3, a side elevation of one of the printing-cylinders,illustrating a construction peculiarly adapted for use in the printingof the longitudinally-striped portion of flags as, for instance, theAmerican flag; Fig. 4, a view of the face of the web as produced by theprinting-cylinder illustrated in Fig. 3; Fig. 5, a longitudinal sectionof the printingcylinder shown in Fig. 3, the section appearing in theplane of line 6 of Figs. 2, 6, 7, and 8; Fig. 6, a vertical transversesection of the same printing-cylinder in the plane of line d of Figs. 3and 5; Fig. 7, a similar section in the plane of line 0 of Figs. 3 and5; Fig. 8, a similar section in the plane of line (Z of Figs. 3 and 5;Fig. 9, a side elevation of the impression-cylinder, and Fig. 10 an endelevation of a portion of the impression-cylinder.

In the drawings, referring for the present exclusively to Fig. 2, 1indicates the side housings of the press; 2, the impression-cylinder; 3,its elastic jacket, as of sheet-rubber 4:, the upper printing-cylinder,carrying a printingform for the upper side of the web or sheet to beprinted, this printing-cylindercooperating with the impression-cylinderand mov ing at the same peripheral rate of speed; 5, the lowerprinting-cylinder, carrying a form corresponding with the lower face ofthe web or sheet to be printed, this printing-cylinder cooperating withthe impression-cylinder and moving at the same peripheral rate of speed;6, inking-roll for the upper printing-cylinder; 7, inking-roll for thelower printing-cylinder; 8, supply-roll of the fabric to be printed; 9,a pair of draw-rolls, the fabric from the sup ply-roll 8 passing betweenimpression-cylinder 2 and upper printingcylinder 4 and thence betweenthe draw-rolls, the draw-rolls and the three cylinders having,preferably, the same diameter and all moving at the same peripheral rateof speed.

Let it be assumed that the opposite surfaces of the web are to beprinted alike in exact register with each other-as, for instance, in theAmerican flagshowing alike on both sides, the two sides being in exactregister,.but one side being the reverse of the other, or, so to speak,one side right-handed and one side left-handed. Assume the press asbeing .employed for the production of the red or striped work of suchflags. In such case both ink-rolls 6 and 7 are to supply red ink totheir respective printing-cylinders.

As the web passes between the impressioncylinder 2 and the upperprinting-cylinder 4 the upper surface of the web will obviously becomeimpressed by the form carried by the upper printing cylinder, suchimpression, however, being, as usual, the reverse of the form whichproduced it. At the same time the lower printing-cylinder 5 prints uponthe .jacket 3 of the impression-cylinder 2 an impression the reverse ofthe form carried by the lower printing-cylinder, andat each turn of thecylinders this impression, carried by the jacket of the impressioncylinder, comes against the lower surface of the web opposite the formupon the upper printing-cylinder and becomes transferred to the lowersurface of the web in reverse of the impression thus brought around bythe impression-cylinder, thus printing both sides of the web. As thejacket of the impression-cylinder received an impression in reverse ofthe form on the lower printing-cylinder and as that impression reverseditself in becoming transferred to the under surface of the fabric, it isobvious that the under surface of the fabric receives an impressioncorresponding precisely with the form on the lowerprinting-cylinder-thatis to say, unreversed. As the two sides of thefabric are to be printed in reverse of each other, it is obvious thatthe two forms, the one on the upper printing-cylinder and the one on thelower printing-cylinder, must be exactly alike, the upper formimprinting itself in reverse upon one side of the fabric, while thelower form sends its impression to the lower surface of the fabricthrough the medium of two reversals. In case the lower surface of thefabric was printed direct from a printing-cylinder, as is the case withthe uppersurface, itis obvious that the two forms would require to bethe reverse of each other, thus involving great skill in the productionof the forms; but in the present case the two forms are identical witheach other, and no skill is required in securing proper correspondencebetween them. The two forms, identical with each other, being secured totheir respective printing-cylinders, it is only requisite that the twoforms be so angularly adjusted upon their cylinders as to secure properregister. This may be done by angularly adjusting one cylinder withreference to the other or by angularly adjusting the form upon one ofthe cylinders. The drawrolls 9 having the same diameters as theprinting-cylinders, it is obvious that if the fresh printing upon theweb causes a set-off on the draw-rolls such set-off will impress itselfin proper place upon the web in correspondence with the printingthereon, and thus do no harm. In the example given-that of the stripepart of the American flag-both the printing-forms would be supplied withred ink; but it is obvious that the system lends itself to printing withvarying colors upon the opposite sides of the fabric. Thus, forinstance, the upper printing-roll may be inked red and the lowerprinting-roll be inked blue, thus printing the upper side of the fabricin red and printing upon the lower side of the fabric anaccurately-registering reverse impression in blue. In the American flag,as an example, there are two colors upon each side, being thus anexample of multicolor printing. If the cylinders of my improved press,as represented in Fig. 2, are to be employed for producing one of thecolorsas, for instance, the red portion of the American flag-then theblue portion will be produced bysubsequent subjection of the runningfabric to a second similar series of three cylinders, the twoprinting-cylinders carrying the forms precisely alike and suited for theblue work, and similarly the web may be subjected to the action of asmany such separate series of three cylinders each as there are colors tobe produced upon each side of the fabric, this method of multicolorprinting by running the fabric through various sets of printing-rolls insuccession not being new.

I will now describe an improved construction for the printing-cylindersadapted for the printing of longitudinal stripesas, for instance, in theAmerican flag.

Referring further to the drawings, 10 in Fig. 4 indicates a strip offabric printed with the red stripes of numerous American flags ofvarious sizes adapted to fill up the fabric; 11, the largest flag of theseries upon the strip, the length of this flag being less than thecircumference of the printing-cylinders and its width being less thanthat of the strip of fabric,-three repetitions of this flag appearing inso much of the strip asis shown; 12, a transverse series of three smallflags, their combined widths equaling the width of large flag 11, andthe length of the small flags 12, plus the length of large flag 11, plusthe space between their ends, corresponding with the circumference ofthe printing-cylinders,there thus being a group of the small flags 12interposed between each of the large flags 1 1; 13, a longitudinalseries of three mediumsized flags disposed alongside thepreviouslymentioned flags, the length of this series of medium-sizedflags, plus the spaces between them, corresponding with thecircumference of the printing-cylinder and coming even endwise with thegroup represented by the large flag 11 and small flags 12; let, a spacetransversely across the strip of fabric between each complete group offlags, by complete group being meant a large flag 11, three small flags12 at its end, and three medium-sized flags 13 alongside the large andsmall flags, each of these groups of large, small, and mediumsizedflags, together with the space 1& between them, representing thecircumference of the printing-cylinders and being repeated on the web ateach turn of the printing-cylinders, and 15 the fields or unstripedportions of the flags, being the portions which are to receive the blueprinting.

Referring to Fig. 4, assume, first, that only the large flags 11 bedesired. The length of such flag is less thanthe circumference of theprinting-cylinder. Henceaspace corresponding with the length of flags 12would be wasted in the operation of printing. Side wastage may of coursebe avoided by usiuga strip of only needed width; butto avoid wastagebetween the ends of the large flags the small flags 12 or any othermatterof suitable size are printed, and for economy in time and labor awide strip is preferably used and flags printed alongside the largeflags. With a printing-cylinderhavingacircumference and length suited toa given very large market size of printed flag it will be found thatthis dimension of printing-cylinder well lends itself to division afterthe general manner indicated in Fig. 4 to the printing of smaller marketsizes without waste of printing-space upon the strip, and the sameprinciple of division may be followed in connection with articles otherthan American flags.

Proceeding with the drawings, 10 indicates the shaft of theprinting-cylinder, which will now be spoken of in the singular, as thetwo printing-cylinders become duplicates of each other; 17, the bearersof the printing-cylinders, having the form of disks fast on the shaft;18, three disks secured upon the shaft of the printing-cylinder andhaving a diameter equal to that of the bearers 17, the peripheries ofthese disks forming printing-surfaces and their widths, spacing, anddisposition on the shaft being in correspondence with the three longstripes of flag 11, (seen in Fig. 4;) 19, four similar disks upon theshaft corresponding in width, spacing, and position with the fourshorter stripes of flag 11, these disksbein g preferably separatelystrung upon the shaft of the printing-cylinder and properly spaced apartby collars or hubs; 20, cut-away portions in the peripheries of disks 18and 19 at points where no stripesare to be printed by those disks, thebottom of these cut-away portions being concentric with the axis of thedisks and their lengths varying according to circumstances, the lengthin disk 18 being represented by the length of flags 12 plus space 14,asseen in Fig. 4,while in disks 19 it is represented by the length offlags 12 plus space 14 plus the length of the field in flag 11; 21,printing-plates secured to the bottoms of cut-away portions 20 of disks18 and 19, the outer surfaces of these plates being circumferentiallyeven with bearers 17 and the printingsurfaces of the disks, theseprinting -plates corresponding with flags 12 of Fig. 4, there being aseparate plate for each of the three flags 12 or one plate for thethree, as desired; 22, three printing-disks strung upon the shaft andcorresponding in width and spacing with the three long stripes of flags13, (seen in Fig.'

4,) these disks forming the long stripes for the three flags of thegroup 13; 23, a bolt extending through the bearers and disks of theprinting-cylinders and serving to dowel the parts in proper angularposition; 24, four printingdisks upon the shaft in correspondence withthe short stripes of flags 13; 25,

cylinder; 30, a ratchet-wheel on an end of the reel-shaft projectingfrom the end of the impression-cylinder, which projecting end is securedfor convenience in turning the reelshaft; 31, a bolt engaging theratchet-wheel,

and 32 the exemplifying transmitting-gear ing of the system, consistingof a receivingpulley communicating motion by spur-gearing to thecylinders and draw-rolls.

Referring to Fig. 2, in applying the jacket 3 to the impression-cylinder2 one end of the jacket is hooked to one series of spurs on thereel-shaft 28 and the reel-shaft partially turned, after which thejacket is brought ing system, a space on which there must be a blank ornon-printing space on the printingcylinders. Referring to Fig. 4, thisspace is utilized at space 14, disposed endwise between flags. Whatevermay be the relationship of the various flags of the groups, otherwisenone of them are to cross the space 14. The blank space 14 may thusserve as the stick-space for all the flags contiguous to it.

Comparing Figs. 3, 4, and 5, it will be observed that all the stripes ofthe large flags 11 and of the medium flags 13 are printed by means ofthe disks and that the small flags 12 are printed by means ofprinting-plates secured in the cut away portions of disks employed inprinting large flags. The space represented by flags 12 and theprinting-plates which produce them may of course be filled up withprinting-plates suited for articles other than flags or, if waste beignored, may be left blank. The disks 22 and 24 for flags 13 may beremoved or may be replaced by others suited for other dimensions offlags, and printing-plates may be used in conjunction with them or not,as desired. Printingplates 21 may be removed and changed withoutdisturbing any disks.
